Definitions

  • the present invention relates to a method of destroying and vaporizing refuse, primarily household waste, the material being fed into the top of a shaft furnace through a gas-tight discharger.
  • the problem of vaporizing refuse according to known methods is that the temperature in the final vaporization step, as well as in the product gas produced in the reactor, is too low. This is partly because refuse has a low heat content and a high water content.
  • One object of the present invention is to eliminate the drawbacks mentioned above and to provide a process which is substantially independent of the water content and the composition of the incoming material.
  • Another object of the invention is to effect a process which consumes less energy than previously used processes and which also results in a valuable process gas.
  • the present invention provides a method of destroying and vaporizing material, comprising pre-drying and pre-vaporizing the material while flowing together with process gas; then feeding the refuse into the top of a shaft furnace through a gas-tight discharger; and supplying in addition to the thermal energy generated during the combustion, an additional controlled quantity of thermal energy by means of blast gas completely or partly electrically heated.
  • the heating of the blast gas may be performed by means of plasma generators, electrical resistor elements and/or indirectly in heat exchangers.
  • At least one plasma generator is used in the method.
  • the gas may be supplied with an extremely high quantity of energy per unit volume, thereby enabling the vaporization and slagging temperatures to be controlled extremely accurately.
  • the heating of blast gas with the aid of plasma generators can be performed in different ways.
  • all or a part of the blast gas can be passed through the plasma generator.
  • a variable but controlled portion of the blast gas can be added downstream of the plasma generator to the rest of the blast gas stream which has by then been heated by the plasma generator.
  • blast gas Normally, air is used as blast gas. However, under normal conditions it is essential to minimize the risk of nitrogen dioxide formation and this might be achieved by heating steam in the plasma generator. The thus heated steam then is used to heat the main gas stream. Other gases might also be admixed, for example different hydrocarbons, recirculated process gas etc.
  • solid fuels such as coal, rubber waste and/or waste oil are mixed into the incoming material, whereby the thermal value of the product gas can be controlled.
  • the extra thermal energy is supplied at several different levels in the shaft furnace. This, together with the use of at least one plasma generator to accomplish the heating, enables the temperatures in the various stages of the process to be controlled quickly and with great accuracy, irrespective of the thermal value and water content of the incoming material.
  • the FIGURE thus shows schematically an installation for performing the process according to the present invention, the shaft furnace in which refuse destruction takes place being designated 1.
  • the incoming material in the form of refuse primarily household waste, optionally with solid fuel such as pit coal and rubber waste mixed in, is fed in at the top 2 of the shaft furnace through a gastight discharger, not shown in detail.
  • the shaft furnace 1 is provided with supply means for blast air at three different levels, namely at 3 above the charging level, at 4 in the mid-region of the shaft, and at 5 at the bottom 11 of the shaft.
  • An annular drum 6 is also arranged about two thirds of the way up the shaft through which product gas can leave the furnace.
  • Plasma generators 7 are arranged to heat the blast air.
  • the blast air is supplied to the shaft furnace through pipes 9 and the product gas leaves the annular drum 6 through the pipe 10.
  • Various heat-exchanger units may be arranged to pre-heat the blast air before it is caused to pass the plasma generators, using the heat in the gas leaving the furnace.
  • these have been omitted in order not to complicate the drawing unnecessarily, particularly as their location and construction is of no decisive significance to the inventive concept.
  • the incoming material is thus fed in through the gastight discharger mentioned earlier, and its temperature gradually increases as the material falls down through the shaft.
  • a liquid slag which is removed through a slag outlet 12.
  • the product gas is removed via the annular drum 6 which, as indicated above, is arranged about two thirds of the way up the shaft. Blast air pre-heated to about 400° C. by means of heat-exchange with product gas leaving the drum 6, is heated by the plasma generator 7 to about 800° C. and then blown through the air supply means 3 above the charging surface 4 immediately above or below the annular ring 6 for the removal of gas, and 5 in the bottom part of the shaft.
  • blast air can be controlled independently of each other, with respect to both temperature and quantity.
  • steam is introduced into the plasma generators 7 through line 8.
  • the main gas stream flows in through line 14 and joins the heated steam downstream of generators 7.
  • the process can be divided into three stages, designated I, II and III, which take place in different zones of the shaft furnace, the approximate limits of these zones being indicated by broken lines in the drawing.
  • the process is in no way limited to three zones; four zones or more can be used.
  • zone I the water content in the incoming material is evaporated and initial vaporization and carbonization of the material occurs as well as partial combustion. Since the final temperature is as low as about 600° C., the hydrogen and oxygen in the water will not noticeably dissociate and vaporized material will to a great extent be combusted to carbon dioxide and water. Admittedly this reduces the thermal value in the product gas, but it also considerably reduces the heat requirement in the continued vaporization process. The water vapour in the gas from zone I also assists in breaking down incompletely broken down hydrocarbons from zone II.
  • the ratio CO 2 /CO is 2:1 and the ratio H 2 O/H 2 is 3:1 in the gas leaving
  • the temperature of the gas leaving is about 600° C.
  • zone II the temperature of the material increases from 600° C. to about 1400° C. while the temperature of the gas leaving zone II is about 1200° C.
  • the volatile portion of the refuse, coal and rubber is substantially fully vaporized in zone II.
  • the heat requirement in zone II is covered by the hot gas from zone III, whereas there is a certain oxygen deficiency. Extra blast air must therefore be supplied to zone II to achieve complete break down of the vaporized hydrocarbons.
  • the hot gas from zone II is mixed with somewhat cooler gas from zone I so that the temperature of the gas flowing out to the annular drum 6 is about 1000° C. This relatively high temperature, together with the water vapor in the gas from zone I, results in any remaining hydrocarbons being rapidly broken down.
  • zone II The process taking place in zone II is controlled with the aid of temperature and oxygen potential in the gas leaving.
  • zone III the temperature rises about 1200° C. to about 1500° C. Only carbonized and inert material enter zone III and the products leaving zone III are therefore carbon monoxide and liquid slag.
  • the heat requirement in this zone is partly met by the combustion heat of oxidation of the carbon to carbon monoxide and also partly by heated blast air. Since the final vaporization temperature is kept as high as 1500° C., all material which cannot be vaporized will be converted to slag and can be tapped off in the form of liquid slag in which all the constituents are firmly bound in a glasslike slag phase, thus considerably facilitating riskfree dumping.
  • the process in zone III is controlled primarily by the slag temperature.
  • Vaporization occurs at high temperature, which results in a pure gas and prevents the formation of tar and unpleasant-smelling substances.
  • Substances which cannot be vaporized are bound in a liquid slag which solidifies upon cooling, making the product odourless, facilitating dumping and preventing heavy metals, for instance, from being leached out.
  • the heat content in the product gas can be controlled by the addition of solid fuels.
